摘　　要：在Reissner-Nordstrm de Sitter黑洞时空背景下,采用Parikh-Wilczek半经典隧穿方法,计算了带有电荷和磁荷的静质量非零粒子在黑洞视界面上的隧穿率.结果表明,黑洞事件视界和宇宙视界处粒子的隧穿率与Bekenstein-Hawking熵有关,真实的辐射谱不再是严格的纯热谱,但这是对Hawking纯热谱的正确修正,结果满足量子理论的幺正性定理.In the background of Reissner-Nordstrom de Sitter black hole space-time, we extend the Parikh -Wilczek＇s tunneling framework to calculate the emission rate of a particle with electric and magnetic charges. Studies have shown that the tunneling rate of particle at the event horizon and the cosmic horizon is relevant to Bekenstein-Hawking entropy, and the radiation spectrum is not strictly pure thermal. This is a right correction to Hawking radiation ,the result is consistent with the underlying unitary theory.
